Blow bull barrel bull barrel with rotational common: 2 Product height diameter size is the same bull barrels, and reflective film is the same, while material products are based on linear low density polyethylene (LLDPE) , crash the extent and degree of heat is the same bull barrels traffic equipment, but the same point so much, how to distinguish the two product? 1, to distinguish the color from pale yellow color blow bull barrels, while Rotational bull barrel color is yellow-orange 2, the age of the blow bull barrels useful life no bull barrels Rotational long life. Plastic bull barrels divided according to different production processes: rotational molding and blow molding two kinds. Blow molding is a method of producing a hollow article of a thermoplastic. Blow molding process consists of five steps: 1 plastic blow molding parison (hollow plastic tube extrusion); 2 in the parison fit the mold will flap closure reflective bull barrels, clamped and cut the parison mold; 3. the cold wall of the mold cavity blown type training, adjust the opening and during cooling to maintain a certain pressure, the mold is opened to remove the part was blown; 5. trimmed burrs to be finished. For thermoplastics many varieties of hollow blow molding, blow molding products of raw materials to meet the functional, performance requirements, blow molding grade of raw material is very rich, the most commonly used material is polyethylene, polypropylene, polyvinyl chloride and thermoplastic poly esters, etc., may also be doped material back mix, used to forming a variety of packaging containers, blow molded products known bottles, buckets and containers of chemicals and the like.
